Refinish reshaped neck heel?

I just reshaped a neck heel from fenderish shape to a flat across shape in order to fit a certain neck pocket. It required removing 1/8 inch of wood in some spots. Its a standard maple/rosewood neck with satin finish and the only things that got touched during sanding were the 3 flat sides of the neck heel (had to shave maybe a millimeter off the sides for width issues.) The final fit came out wonderful. So how do i refinish this and seal that wood?

Grab a can of Deft lacquer and spray a light coat on the heal just to seal the wood. It doesn't have to be perfect being that its on the heal, you just don't want the maple to turn gray because there is no finish on it.
